Product details
Overview
The femometer Ring Gen1 is a compact wearable designed to help you understand daily temperature patterns, sleep quality, and cycle trends. We recommend using a sizing kit before purchase to help you find the most comfortable fit, ensuring reliable readings and a smoother wearing experience.
Built for everyday wear, the ring features a slim 2.7 mm profile and a premium ceramic exterior with an aluminum core. It is rechargeable and waterproof, so you can wear it during daily activities or a restful night without worry.
How it works
Wear the ring on your finger to monitor temperature in real time. The companion app automatically syncs your data and creates personalized charts, helping you observe patterns and plan your routine with greater clarity.
- Real-time temperature tracking for clear trend visibility
- Automatic data synchronization to the app for seamless charting
- Customized fertility charts that reflect your unique cycle
For Android users, download the Android app, and for iOS users, install the iOS app. The app accumulates nightly data to present approachable insights without overwhelming details.
Key benefits
- Lightweight design and comfortable wear for daily use
- Upgraded sensors for sharper temperature readings
- Sleep insights with stage breakdowns and practical recommendations
Designed to accompany your routine, Gen1 emphasizes durability and ease of use. The experience is informative rather than prescriptive, inviting you to consider how data trends might fit your plans without promising outcomes.
Getting started
Begin with the sizing kit, then download and pair the app to start recording. Wearing the ring consistently, even during sleep, helps build richer data over time.
Care and longevity
Maintain the ring by keeping it clean and charged. Its waterproof construction supports everyday wear, from workouts to lounging, while preserving its functionality over time.
